You clot me!

A few days ago I tried observing a wet mount of my own blood. The very same slide now has a large number of fibrin networks, the end result of the various steps of pathways that lead to clotting of blood. These fibrin networks not only prevent leaking of blood out of a vessel, they…

Bloodletting for curiosity…

While washing some slides, I ended up giving myself a cut to the finger by mistake. The drop of blood that came out and also the slides reminded me about Field staining I performed during practical sessions at college. This made me prepare a wet mount of that drop (usually smears are made). And this…

Foldscope view of Marigold leaves infested with spidermites

Marigold is prized for its bright colours easy to grow nature and require little care. The plant is hardy and perfect for landscape settings and home gardens. While marigolds are typically pest-free and not bothered by most insects, occasional problems may arise with a few common garden pests. I could see some powdery appearance on…

A flagellate morphing it’s shape РDistigma proteus

What an incredible flagellate did I stumble upon Today, while wandering through my favorite hiding spot; a swamp. I believe this is Distigma proteus – what’s remarkable is the body shape change which was continuous. If you watch is carefully; a remarkable transformation is happening. I am trying to isolate as many of them and…

Rheinberg illumination for Foldscope

123 years ago Julius Rheinberg invented a variation of the darkfield microscope by adding color to it. Essentially it involved using various combinations of transparent colored papers set up in a way where diffracted light would be of one color and the direct light falling on the object of another. Typically annular rings are made…

Ammonium dihydrogen phosphate

This molecule is used as a fertilizer. It is also used as a fire extinguisher, a piezoelectric transducer and in children’s crystal growing kits (where I obtained it). I took this photo with polarizing light and then rotated the polarizer to get the next picture.

A suggestion : To use dyes that rotate the plane of polarised light

It’s been quite a long while since I last posted here… A small play with polarizing filters and the fern rhizome slides provided in deluxe foldscope kits, I came up with these images :: I’d want to know which dyes were used in staining as these seem to rotate plane of polarised light. It’d be…

Aspirin Crystals Under Polarized Light

I have always been interested in polarized light and wondered if the foldscope could be made to incorporate it. Knowing nothing about optics, I was pretty sure that the viewing situation would be too compressed for this to work…but I still wanted to try. I purchased two plastic, linear polarizing sheets from Edmonds Optics.¬† I…

The last two images is of a Dandelion and a Orange Double Lilly from my backyard.The first two images is from the slides I made of the petals of each while using the Foldscope.Not very clear. My goal is to compare the petals of each.

Magnesium Sulphate – Polarizing movie

For a few pennies, I was able to get some Epsom salts. I added water and let it dry on the slide and then viewed with polarizing filters. Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early….

Magnesium Sulphate (Epsom Salt) crystals.

Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early. It is also called Epsom salts and used for soaking and skin healing.

Serendipitous Dance of Polarizing Crystals – MgSO4

For a few pennies, I was able to get some Magnesium sulphate. I mixed in water and allowed it to dry on the slide. I thought it had dried, but when I looked at the clip I realized there was a drop of water (at about 7 seconds into the clip) at the top of…
